SAN D-BAN Dz SPECIFICATION forming part of Letters Patent No. 406,073,dated July 2, 1889.

Application tiled April 8,1889. Serial No. 306,418. (No model.)

To all whom t may concern:

.lle it known that we, FRANK lVERNER and RICHARD OEHnieEN, both ofMinneapolis, Hennepin county, Minnesota, have invented certain new anduseful Improvement s in Sand- Bands for Yehiele-Wheel lllubs, ot" whichthe following is the specification.

Our invention relates to the hubs ot' wheels ot' ordinaryhighway-veliieles, and its object is to provide means to prevent sandfrom working into the axle-boxes otl the wheels and the waste oil orgrease from oozing out Of them, and it consists, generally, in theconstruction and combination hereinafter described, and particularlypointed out in the claims.

In the drawings, forming part of the specification, Figure l is acentral longitudinal section of a wheel-hub tilted with our improvedlsand-bands. Figs, 2, il, i, 5, 1S, and '7 are details.

In the drz'lwings, 2 the hub.

ii is the axle-box, secured in the hub inthe usual manner, and l is theaxle, oi' ordinary form and material.

5 is the axle-nut, adapted to bear, preterably, against the end ot' thebox 53, and to iit into a suitable recess in the end ot' the hub.

6 and 7 are the hub-lmnds, fitted, respectively, on the outer and innerends ot the hub. They are screw-threaded on their outer surface, and arepreferably provided with a series ol' points or spurs lll, which areadapted to be driven into the shoulder ll ot' the hub, and to firmlysecure the band in place.

The sand-band S has a closed or solid end, and tits over and entirelycloses the opening in the outer end of the hub, and its inner surface isscrew-threaded to engage with and mesh with the threads on the outersurface otl the hub-band. The outer end of the sand-band o is preferablyflanged or cupshaped, and is provided with a central projection or head1;), corresponding perfectly in form and size to the nut 5, by means ot'which the sand-band 8 may be screwed and unserewed with the same wrenchthat is used for thc nut 5. ',lhe flanges 1.5 preferably project thesame distance as the head 1.2,and serve to give an ornamental iinish tothe hub. The sand-band El has its inner represents the body oi' surfacesimilarly screw-tlireaded to engage with. the hub-band 7. The interiorot' its outer end is preferablyv flaring7 to aliford room for it toproject over the axle-bed without touching it and to prevent an entranceof sand. to the shoulder Il ot the axle. In each ot' the sand-bands Sand i) there preierably an annular space I5 between the end of the huband the closed end ol' the band and the shoulder I7 ot' the band t),which serves as a receptacle for the waste oil and grease which oozesout ot' the axle-box, and which with the ordinary construction smearsthe end oi' the hub.

In order to easily screw and unscrew the sand-band Si, we prefer to cutinto its projecting edge 'opposite rectangular notches 0r slots lt, andto shape the .handle of vehiclewrench to iit into these slots and toserve as a lever to turn it in the desired direction. A wheel-hubtit-ted with these bands is fully as ornamental as with the ordinaryband, and can be slipped on or oit' the axle without moving the band Si,which nevertheless perfectly protects the shoulder ll. from contact withsand and mud. 'lhe band S is preferably either right or left threaded tocorrespond with the direction olf thread on the inclosed nut.

We claim as our inventionM l. In a wheel-hub, the combination, with theend hub-bainls l' and 7, having their outer surface screw-tlireaded, olthe bands 8 and il, having their inner surface screwthreaded and adaptedto surround and engage with the bands f3 and 7, respectively, the band ohaving a closed end and the band El a `flaring and open end, and bothbands formed with the recesses l5 to form waste-oil receptacles,substantially as described.

2. The combination, with a wheel-hub, ol the screw-threaded bands G and7, provided with the spurs l O, of the closed screw-threaded band S,adapted to tit upon and engage with the band if) and having the flangel) and the head Ii inclosed by said band, and the screwthreaded band i),adapted to lit upon and engage with the band 7 and provided with theshoulder VlT and the slots lli, substantially IOO described.

3. The combination, with the hub, ol the hemd 7, secured the-roto andoxterorly screwthreaded, and the band 9, interiorly threaded to t thethreads of the band 7 and 'formed with an oil-space 15, and a shoulder1.7 botwoen said space and the end of the band, the portion of the bandfrom said shoulder outward boing flaring, substantially as `and for thepurposes sot forth.

In testimony whereof we hzwehorounto sot our hands this 3d day of April,'1889.
